One of the objects of the invention istoprovide an attachment vfor containers, .so construct- 4ed and arrangedasv to controllably'discharge definitely measured quantities .of the. contents of the latter.A in a sanitary manner and Without rotativelv. mounted dispensing v.member controlling thedischarge therefrom, said'dispensing a dispensing. device of thecharacter.mentioned having means normally functioning.to..maintain thedispensing member ina -closedpositiona with the measuring. chamber in position to receive a charge, andito prevent. accidental. discharge -of the `contents ofthe container. :A further .,ob-

'forth and particularly pointed out in the claims.

ASaid bearing isalso 5. provided VVVwith a discharge slot .32 at vrightanglesl tof the opening I5 and invposition toregister with ...said pocket I8.

v It willibe noted-that the-edgesofl recess -21 are so disposed as to cooperate with thestop .-29 .to .limit rotative `movement of the shell Il in both..-30 directions. vmIn .-the normal vclosed position, the

- pocket :I8 uegisters-'With the opening I5. andfin fthe other position the pocketregisters with the vdischarge .opening v32.

In operation, the pocket I8 is normally maintained in register with the opening I5, so that by inverting the body the said pocket will be lled with the powdered material. 45 By then pressing aga-inst the thumb piece 3l the shelll I'I may be rotated Within the bearing I6 against the tension of spring 23, a distance limited by the walls of the recess 21, which will bring the pocket in register with the discharge opening 32, whereupon the contents of the pocket will be discharged. Upon release of the pressure against the thumb piece, the spring 23 will return the shell to its normal position with the pocketin register with opening I5. It is to be understood that the various parts may be secured together by brazing, Welding or any other desired manner.

The advantages of the invention Will be readily understood by those skilled in the art to which it belongs. For instance, it Will be observed that a very simple and inexpensive form of dispensing top is provided, constructed from stamped sheet metal, thereby providing a cheap and simple structure.` A further advantage is that the device is so constructed that it may be connected with any type of container, and While in position Will permit of the ready dispensing of measured quantities of the contents of the container.

, use, what is claimed is:

l. In a dispensing apparatus, a top member provided With a cylindrical bearing sleeve open at both ends and provided with circumferentially .disposed inlet and outlet'openings respectively, a sleeve-like dispensing shell rotatively Amounted Within said sleeve and having a radially disposed depression to provide a measuring pocket adapted to register with said openings,

' vsaid shell being closed at one end and having iico means for closing the adjacent end of said sleeve,

'f mentioned end Wall and also closing the adjacent end of said sleeve, said actuator member being secured to the last mentioned closed end Wall of the shell in such manner that rotative movements may be imparted to the shell by move- 'ments of the actuator, and means located between the actuator member and said last mentioned wall of the shell for yieldingly holding the shell in such position that the measuring pocket thereof will normally be in register with s aid inlet opening.

2. In a dispensing apparatus, a top member provided With a cylindrical bearing sleeve open at both ends and provided with circumferentially spaced inlet and outlet openings, asleeve-like dispensing shell of thin metal rotatively mounted within said sleeve and having a radially disposed depression to provide a measuring pocket adapted to register With said openings, oneend of sai-d sleeve being closed by an integral end Wall provided with an annular flange so positioned as to close the adjacent end of said sleeve, an end Wall closing the other end of said shell and located Within the same, an actuator member located adjacent to the last mentioned end Wall and also closing the adjacent end of said sleeve, said actuator member being secured to the last mentioned closed end Wall of the shell in such manner that rotative movements may be imparted to the shell by movements of the actuator member, and means located between the actuator member and said last mentioned end Wall of the shell for yieldingly holding the shell in such position that the measuring pocket thereof Will normallybe in register with the inlet opening.

3. In a dispensing apparatus, a top member provided with a cylindrical bearing sleeve open at both ends and provided with circumferentially spaced inlet and outlet openings, a, sleevelike dispensing shell of thin metal rotatively mounted Within said sleeve and having a depression therein providing a measuring pocket adapted to register with said openings, said shell being closed at one end by an integral end Wall having portions of the metal bent upon itself to provide an annular flange adapted to close the adjacent end of said sleeve, a separate end Wall closing the other end of said shell and secured thereto, said last `mentioned end wall having an axially extended central boss, an actuator member also formed of thin metal located adjacent to said boss, said actuator member having a chamber therein adapted to enclose said boss, and a portion secured to the boss-carrying wall in such manner that said shell may be rotated by movements of the actuator member, said actuator member also closing the adjacent end of said sleeve, and a'spring encircling said boss and having its ends respectively engaging said actuator member and said bearing sleeve.

4. In a dispensing apparatus, a top member providedvvith a cylindrical bearing sleeve open at both ends and provided with an inlet opening and an outlet opening at circumierentially spaced positions, a sleeve-like dispensing shell of thin metal rotatively mounted within said sleeve and having a circumferential depression to provide a measuring pocket so positioned that it may be caused to selectively register with said openings, said shell being closed at one end by an integral `Wall having portions bent back upon themselves to provide an annular ange engaging and closing the adjacent end of the bearing sleeve, a separate end Wall secured Within said shell contiguously to the other end thereof in such manner as to close the latter, said last mentioned end wall having an axially extended centrally disposed boss,l acircular actuating member having an inturned annular flange secured to said separate end Wall and of such diameter as to close the other end of said bearing sleeve, said flange having an opening to receive said boss, said flange also having an arcuate recess therein, said sleeve having a stud projecting into said recess, and a spring encircling said boss, one end of said spring engaging said sleeve and the other end thereof engaging said actuating member.
